RGG1 encodes a type-A Gγ subunit. a Gene structure of RGG1. b Phylogenetic tree of Gγ subunits from rice, Arabidopsis and maize. c Interaction between RGG1 and RGB1. Scale bars, 100 μm. d Yeast two-hybrid assay. In this assay, RGG1 was used as the prey (GAL4-AD, AD) due to its autoactivation ability, and RGB1 was used as the bait (GAL4-BD, BD). Δ represents deleted protein parts. The numbers show the different lengths of each truncated protein. NLS is the predicted nuclear localization signal. GGL is the G gamma-like domain. U represents the unknown domain
